It's from Andy Katz' ESPN blog (which is subscriber only) so I can't cut and paste it, but the gist of it is have all Division I players available for the draft and give the kids 10 days to return to school if they don't like where they went in the draft.

I never thought of that and it's a great idea. It puts the power back in the NCAA's hands. A radical idea that actually makes sense. The problem I see is unlike baseball, the NBA only has 2 rounds, but that's their problem not the NCAA.
